Could someone please tell me where are the logging information located for p2 director?

I am using p2 director to install/uninstall features. It looks like install and uninstall went through without seeing any error. But when I open eclipse IDE, some of the features are either not installed (should be installed) and not uninstalled (should be uninstalled). I would Iike to look into the logging or enable detail level of loggings. But I could not find where the logging is and how to enable the detail loggings.
